BACKGROUND:Daclizumab can be special y combined with the inerleukin-2 receptor on the surface of activated T cells in human body, and this method can reflect the close of interleukin-2 receptor thus inferring the effect of induction therapy. At present, the daclizumab has been widely used in renal transplantation, but there is no consensus on its clinical application in liver transplantation. OBJECTIVE:To investigate the expression of serum CD25+T cells and soluble interleukin-2 receptor in the patients receiving daclizumab for liver transplantation during perioperative period. METHODS:A total of 58 patients received orthotopic liver transplant for the first time were included and then the patients were randomly divided into two groups:control group (n=28) and treatment group (n=30). The patients in the two groups were treated with tacrolimus, mycophenolate mofetil and corticosteroids triple immunosuppressive regimen. The patients in the treatment group received immune induction therapy with daclizumab, and the patients in the control group did not receive daclizumab. RESULTS AND CONCLUSION:Flow cytometry and enzyme-linked immunosorbent assay showed the expression levels of CD25+T cells in the treatment group were significantly lower than those in the control group at different time points after liver transplantation (P<0.01);and the expression levels of soluble interleukin-2 receptor in the treatment group were lower than those in the control group during transplantation and at the first day after transplantation (P<0.05, P<0.01). At 6 months after transplantation, the incidence of acute rejection was decreased in the treatment group (P<0.01). The results indicate that daclizumab can effectively suppress the expression level of CD25+T cells, as wel as the expression level of soluble interleukin-2 receptor in the peripheral blood in the early stage of liver transplantation, thus effectively reducing the rate of acute rejection.

Objective To explore 24-hour ambulatory blood pressure of patients with cervical spinal cord injury. Methods 42 patients with cervical spinal cord injury and 45 patients with thoracic-lumbar spinal cord injury were included. Their 24-hour ambulatory blood pressures were monitored. Their day systolic blood pressure (dSBP) and day diastolic blood pressure (dDBP) when seating and standing, night SBP and DBP, and SBP descending rate at night were compared. Results There were significant differences in dSBP and dDBP when standing, and SBP descending rate at night between 2 groups (P<0.01). There was significant difference in dSBP between seating and standing position in patients with cervical spinal cord injury (P<0.01). Conclusion There is orthostatic hypotension in cervical spinal cord injury patients and their SBP descending rate at night is upside down.

Objective To analyze the efficacy and safety of different chemotherapy regimens for treatment of progressive patients with small cell lung cancer (SCLC) brain metastasis after radiotherapy. Methods 96 SCLC brain metastasis patients with progressive intracranial lesions after radiotherapy were divided into four groups: carmustine group (Group A, 28 cases), temozolomide group (Group B, 19 cases), topotecan group (Group C, 24 cases) and no chemotherapy group (Group D, 25 cases). Results In terms of brain metastases, there were no complete response cases in the whole groups. The rates of partial remission (PR), stable disease (SD) and progression of disease (PD) in Group A were 17.8%(5/28), 53.6%(15/28) and 28.6 % (8/28), respectively, the response rate (RR) of intracranial lesions was 17.9 % (5/28), and disease control (CR+PR+SD) rate was 71.4%(20/28). The rates of PR, SD and PD in Group B were 15.8%(3/19), 63.2 % (12/19) and 21.1 % (4/19), respectively, the RR of intracranial lesions was 15.8 % (3/19), and disease control rate was 78.9 % (15/19). The rates of PR, SD and PD in Group D were 8.3 % (2/24), 54.2 %(13/24) and 37.5 % (9/24), respectively, the RR rate of intracranial lesions was 8.3 % (2/24), and disease control rate was 62.5 % (15/24). In Group D, there was no response case, and 20 patients with PD (80.0 %) were found. The median progression-free survivals (PFSs) were (3.64 ±0.43) months, (4.68 ±0.49) months,(3.58 ±0.50) months, (2.60 ±0.31) months in Group A, B, C and D, respectively, and the median overall survivals (OSs) were (18.80±1.74) months, (18.76±1.85) months, (19.10±1.64) months and (9.64±0.84) months, respectively. The median OS of Group A, B or C was longer than that of Group D (P=0.002). The differences of grade Ⅲ-Ⅳhematologic toxicities among the four subgroups were not statistically different. Patients in Group B had better tolerance to nausea and vomit. In Group D, the central nervous system symptoms such as fatigue and headache occurred frequently. Conclusions The response rate and OS of SCLC brain metastasis patients with progressive intracranial lesions after radiotherapy are improved after chemotherapy, however, PFS is not significantly prolonged. The efficacies of carmustine, temozolomide and topotecan are similar in short and long term, besides, temozolomide shows less adverse events and a higher disease control rate. The application of chemotherapy that could penetrate the blood-brain barrier can improve the efficacy on SCLC brain metastasis patients with progressive intracranial lesions after radiotherapy with well tolerance.

Antibody arrays, as a specific subset of protein arrays,are now used in a wide variety of applications. Although having evolved into indispensable tools for proteomic studies, they seems to be still at the middle point on the way to the final destination to have the antibody arrays with high sensitivity, minimized size and wide dynamic detection range to meet the needs for the detection of different samples. This article reviewed the recent development regarding how to improve the detection sensitivity of the antibody arrays.

Objective To determine the relationship between serum vitamin B_(12)(VB_(12))level and multiple sclerosis(MS).Methods The pertinent articles of the VB12 and the case control studies of MS were retrieved comprehensively by manual retrieval and computer retrieval.The methodology quality of the retrieved artilces were evaluated,and the arcb'cles were screened.Heterogeneity test was performed.The valid data was extracted and analyzed by Stata 10.1.Results In this study,9 studies were included.A total of 807 subjects were enrolled,including 414 patients and 393 controls.The Meta-analysis showed that the serum level of VB_(12) in patients with MS was lower than that in controls(standardized mean difference-0.24,95% CI-0.39 to-0.10).The sensitivity analysis indicated that the result of meta-analysis was reliable.Conclusion The serum level of VB_(12) might be associated with MS,and the deficiency of VB_(12) may contribute to the development of MS.

The divergent projections in the bulbo-cerebellar system of rats were studied by double fluorescein labeling method. 2 ?1 of 2％ Fast blue (FB)were injected into the cerebellar cortex of left anterior lobe, 32 hours later, 2 ?l of 2％ Nuclear yellow (NY)were injected into the cerebellar cortex of right anteior lobe. The animals were allowed to survive 16 hours thereafter. Intracardiac perfusion were performed with 10％ formalin in 0.1 mol/L phosphate buffer. The cerebellum and medulla oblongata were removed and serial sections at 20 ?m were cut by cryostat. One of every two sections was preserved for fluorescence microscopic observation. The results identified that there was no intereonnection between the anterior lobes of two cerebellar hemispheres and the anterior lobe of cerebellum received afferent projections from much more nuclei of the medulla oblongata than previous description. The FB or NY single labeled and FB/NY double labeled cells were observed in the nucleus reticularis lateralis, subnucleus reticularis ventralis, nucleus raphe obscurus, nucleus prepositus hypoglossi, nucleus cuneatus lateralis, nucleus spinalis nervi trigemini and nucleus olivaris aceessorius dorsalis. The double labeled cells accounted for 23％ of total labeled cells except the nucleus olivaris inferior. The results mentioned above suggested that the cerebellum receive multiple afferent connections originated from the medulla oblongata, and the divergent projections further amplify the information-receiving areas in the cerebellum, and synchronize the activities of both cerebellar hemispheres.

OBJECTIVE:To investigate the clinical efficacy and safety of atorvastatin calcium combined with probucol in the treatment of atherosclerosis. METHODS:A total of 80 patients with atherosclerosis selected from the Affiliated Hospital of Sichuan College of TCM during Jan. 2015-Jan. 2016 were randomly divided into control group and observation group according to random number table,with 40 cases in each group. Control group was given Probucol tablet 0.5 g,every 2 days. Observation group was ad-ditionally given Atorvastatin calcium tablet 20 mg,qd,on the basis of control group. Both groups were treated for consecutive 24 weeks. The levels of blood lipid,arterial plaque size and thickness before and after treatment,life quality score before treatment and 3 months after treatment were observed in 2 groups;and the occurrence of ADR was recorded. RESULTS:Before treatment, there was no statistical significance in blood lipid,arterial plaque size and thickness or life quality score between 2 groups(P>0.05). After treatment,the levels of TC,TG and LDL-C,arterial plaque size and thickness in 2 groups were decreased significant-ly,while HDL-C level and life quality score were increased significantly;the improvement of above indexes in observation group was significantly better than control group,with statistical significance(P<0.05). There was no statistical significance in total inci-dence of ADR between observation group(12.50%)and control group(15.00%)(P>0.05). CONCLUSIONS:Atorvastatin calci-um combined with probucol in the treatment of atherosclerosis can reduce blood lipid level and get thrombolysis,and contribute to the recovery of living ability with good safety.
